  • Patent number: 11337588
    Abstract: An endoscope (1) having a handle with a handle housing (2) and an insertion tube (3) extending from said handle (2) and terminating in a tip part (4) at the distal end of the endoscope (1). A working channel and having a distal end and a proximal end extends within the insertion tube (3). The endoscope further comprises motion transfer means (53, 54) extending within said working channel and adapted to operate a tool (55) at the exit port of the tip part (4) in response to the activation of an operating member (22). The working channel comprises a generally tubular working channel wall. The distal working channel end comprises an exit port at the tip part (4) at the distal end of the endoscope (1). The proximal working channel end comprises an end sealing means accommodated within the handle housing (2). An entry port is provided between the distal working channel end and the proximal working channel end.

  • Patent number: 10624617
    Abstract: An endoscope (1) having an operating handle comprising a handle housing (2) and an insertion tube (3) extending from said handle towards a distal end of the endoscope (1) and terminating in a tip part (4) at the distal end of the endoscope (1). The endoscope (1) comprises a tool operating member (22) for operating a too (55) at the tip part (4). A control means connects the tool operating member (22) and the tool (55), so as to allow linear movement (55) of the tool in response to activation of said tool operating member (22). The control means is adapted to also perform a compound movement of said tool (55) in response to activation of said tool operating member (22), where the compound movement comprises a task movement in addition to said linear movement.

  • Patent number: 10314993
    Abstract: A laryngeal mask (1) comprising an air-way tube (2) and a mask portion (6) with an inflatable cuff (8) which is arranged around the airway tube (2) at the distal end thereof. A gastric tube (12) which extends at least partially along the outer surface of the airway tube (2), penetrates through the wall of said inflatable cuff (8) at a first location, extends through said inflatable cuff (8), and ends in a connection to an opening (12) in the wall of the cuff at a second location at the tip part of the laryngeal mask, so as to provide a passage through said circumferential cuff. With respect to a central mirror symmetry plane said gastric tube extends along the outer surface of the airway tube (2) in an asymmetrical manner, through said inflatable cuff (8) at the first location arranged asymmetrically with respect to said central plane, through said inflatable cuff (8), and ends in the connection to the wall of the cuff (8) at the second location at the tip part.

  • Patent number: 10149955
    Abstract: A laryngeal mask for use in a patient includes an airway tube having an inner lumen and a distal end; and a mask portion connected at a proximal end thereof to the distal end of the airway tube and having a distal tip opposite the proximal end. The mask portion includes an inflatable cuff including an anterior cuff surface configured to contact the patient's tissue when the inflatable cuff is inflated; and a wedge portion including a stabilization surface and two walls connected to the inflatable cuff and extending therefrom toward the stabilization surface, the stabilization surface extending from the distal tip of the mask portion toward the distal end of the airway tube at a wedge angle of between about 12 and 30 degrees, the wedge angle formed between the stabilization surface and the anterior cuff surface when the inflatable mask is inflated, whereby the stabilization surface is transversely and longitudinally substantially flat to stabilize the laryngeal mask in use.

  • Patent number: 7694682
    Abstract: The invention relates to a laryngeal mask (1) comprising at least one airway tube (2) and a mask portion (3), which mask portion (3) comprises a top face (4) and a bottom face (5), said bottom face (5) comprising a lumen (6) that communicates with the tube (2) interior (7), and said top face (4) comprising a closed transition face (8), and said mask portion (3) being at least on the bottom face in the periphery delimited by an inflatable cuff (9), and said mask portion (3) comprising a joint throughout the entire internal circumference of the cuff (9), facing towards the lumen (6) and for providing a closed cuff. Hereby a product is provided which is formed integrally with regard to mask portion and airway tube portion thereby eliminating the risk that the two parts are separated in use.
